PENCIL-SHARPENER.

Patented Sept. 25. 19.06.

Application filed September 29, 1905. Serial No. 280,694.

To all whom it may concern:

Be it known that we, FRANK J. STUTES- MAN and BENJAMIN F. FERTICK, citizens of the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented new and useful Improvements in Pencil-Sharpeners, of which the following is a specification.

This invention is a pencil-sharpening machine having a rotary cutter mounted upon an arbor in a circular casing containing a rack with which a pinion on the arbor meshes. The top or cover of the casing contains a thimble in which the pencil is inserted andV central vertical section.

lteferring'specifically to the drawings, 6 indicates an outer cylindrical casing having a bottom 7 and an internal annular rack 8, extending around the side wall thereof. The casin is mounted upon rubber feet 9, so that it WilInot readily slip out of position when in use. At the centerof the casing is a vertical sleeve 10, within which fits the spindle 11, dependin lr from the top 12. The spindle 1 1 eX- tends tthrough the bottom-of the casin and has a roove 13, which receives a lato 14, pivote to the bottom of the casing'. When -the latch is engaged, the spindle and cover are held in position and lift is prevented.

Mounted upon` the cover 12, in an o ening therein, is a ring 15, which is flange at its outer edge, as at 16, to embrace the edge of the cover at the opening. The opening is circular, so that the ring turns freely therein. Projecting upwardly from the ring are several spring-iingers 17, encircling which is a thimble 18, which is movable to a limited or suiiicient extent u and down thereon. At the top the bore o thethimble is tapered or ,Y beveled, as at 19, and this beveled portion vrests against the spring-fingers. Between the fingers are shorter. ri 'd guide-pieces 17,

extent of its movement being limitedbyv a screw 18B, which projectsfrornv the thimble Fig. 2 is a` into a vertical slot 18b in o'ne of the guideieces.

RivetedI to the under side of the cover 12 is a bracket 20, having two arms which support the spindle 21 of the wheel of blades 22. At its outer end the spindle has a inion 23, which rests upon and meshes wit the rack 8. The hub 24 of thewlieel fits overasquared portion 25 of' the spindle 21, so that rotation of thewheel is effected and axial movement along the s indle is permitted. Pressing behind the w eel is a coiled spring 26.

In operation the pencil (indicated in dotted lines at 27) isV inserted through the thimble and ring on the cover of the machine. The Wheel 22 is so positioned that the pencil comes against the same at the proper angle to give the desired point to the pencil. Downward pressure on the thimble 18 contracts the fingers 17 against the pencil, holding the same frml The thimble and pencil are then revo ved, carrying the inion around the rack and revolving the lades against the side of the pencil. The spring 26 f causes the proper pressure of the blades against the point of the pencil to cause them to take into the wood and cut the same. The cuttings and dust fall into the casing below, where they are retained until it is necessary to empty the same, which can be done by unlat'chin the latch 14 and removing the cover. When tltlie pencil is sharpened, the thimble 18 is released and the ingers 17 open to permit the pencil to be pulled out.

A noticeable feature of the wheel of blades is that it is reversible-that is, the blades are Asharpened on both sides, and when one'of the edges becomes dull the Wheel can be taken ofi' the s indle and reversed, so that the other edge wi l be presented to the pencil.

What we claim as new, and desire to secure by Letters Patent, is

1. A pencil-Sharpener comprising a casing having a rotatable cover thereon, a pencilholding chuck mounted on the cover and forming a handheld to rotatethe cover, a cutting device within the casing, carried .by the cover, and means for operating the cutting device by the rotation of the cover.

2. A pencil-Sharpener` comprising a casing having an lannular rack therein, a rotatable through which a pencil may be inserted,

IOO

means onthe cover to grip and hold the pencil, and a wheel of blades carried on the under side of the cover, belowsaid opening, and having a pinion meshing with the rack.

3. A pencil-Sharpener comprising a cylindrical casing having a central tube and an annular rack, a rotary cover having a spindle depending through the tube and an opening provided with a holding device through which the end of the pencil is inserted into the casing, and a wheel of blades su ported on the under side of the cover, belbw the opening, and having a shaft with a pinion meshing with the rack.

4. A pencil-Sharpener comprising a cupshaped case having a rotatable cover provided witha perforation, a handle having one end secured in said erforation and having therethrough a longltudinal opening, ad-A justable means arranged in said handle and adapted-to engage and hold a pencil, an annular row of teeth projecting from lthe inner ing bearings in said frame and carrying a pinion engaging said teeth, and a rotary cutter mounted on said axle and adapted to rotate therewith.

5. A pencil-Sharpener comprising a casel having a vertical annular wall and arotatable removable cover provided with a perforation, a vertical handle rotatably secured in said perforation and provided with a longitudinal opening to receive a pencil, adjustable means arranged 1n sald handle and adapted to hold a penc1l,'an annular row of teeth connected with the inner face of the said wall, a frame secured to the under face of said cover; an axle mounted in said frame, a pinion secured on one end of said axle and adapted when the cover is rotated to be engaged and rotated by the said teeth, and a rotary cutter having a hub slidably mounted on said axle, all for the purpose described.

6. A pencil-Sharpener comprising a casel having a base, a vertical annular wall, and a removable rotatable cover. having a perforation; a vertical handle rotatably secured in said erforation and provided with a longitudinalpopening to receive a pencil; a chuck arranged in said handle and adapted to hold said pencil; an annular row of teeth formed on the inner face of said wall; a frame secured to the under side of'said cover g an axle mountf ed in said frame and having a pinion adapted face ofthe wall of the case, a frame connected f with the under side ofthe cover, an axle havto be engaged and rotated by said teeth; and. a rotary cutter slidably mounted on said axle,

all for the purpose described.
